IMPROVEMENT IN VEHICLE-HUBS.

Specification forming part of Letters Patent No. 173,833, dated February 22, 1876; application tiled May 2s, 1875.

To all whom it may concern Be it known that I, JOHN G.- WANDs, of

Nashville,in the county of Davidson and State of Tennessee, have invented a new and valuable Improvement in Metal Wheel-Hubs;

and I do hereby declare that the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation ot' a longitudinal central section ot' my hub, and Fig. 2 is a plan view of the same.

This invention hasrelation to improvements in metallic hubs for vehicle-wheels 5 and the nature of the invention consists in a hub pro vided with angular corrugations for the reception of the ends of the spokes, in combination with flanges having radial angular ribs on their inner surfaces, which lie directly opposite each other and in line with the corruga- 4 suitable distance apart, between which the ends of spokes D are designed to be secured. The inner end of hub O has a screw-threaded rabbet,c, formed thereon, adapted to be received into the open front end'of sleeve B, and to be screwed therein by a movement opposite to thatwhich the hub would receive duringV the progress of the vehicle. The extreme inner end of hub G abuts against collar o, the same` being-thus inclosed between it and sleeve VB, so that the hub is eii'ectually secured upon its spindle, and the outer end of the body ot' the hub being closed, the introduction of sand or mud between the said hub and the spindle is effectually prevented. The bore of hub O is either cast in the original mold and.- subsequently bored out smooth, or the hub may be cast solid and the bore subsequently made by a suitable cutting-tool, as I may elect. The hub may be made of wrought, cast, or malleable iron, as may be found most desirable. The inner surfaces of flanges d are provided with radial and preferably angular serrations, c, which are cast with the hub, and are exactl y opposite each other, and the body of thehub between iianges d is longitudinally corrugated, the depressions of the said corrugations j' being at the foot of each pair of serrations c, as shown in Fig. 2, so that when the spokes, which I designate by the letterD, are driven between serrations c, their lower ends, which are of corresponding shape therewith, will be received in the depression between corrugations f. In practice, the end of spokes E, designed to be inserted into the mortise formed by corrugatious fand serrations @,will be correspondingly tenoned to tit therein, and their lower ends will be split and forced outward and inward into recesses formed at the base of flanges d by means of a wedge or wedges, i, which will be forcibly driven up into the spoke when itis forced home into thev hub. By this means the spoke is rigidly held against endwise displacement, and its foot being stepped between corrugations f, and its lateral edges between serrations e, thus preventing vibration and axial rotation, a means of securing the spokes to the hub, independent of the restraint ot' the fellies and tire, of unexceptional excellence is obtained. Y With a view to strengthening flanges d. tierods j, of suitable strength, are passed through registering perforations in its serrations c, between the tenons of the spokes, and they are clinched upon the outer surfaces of the said flanges, as `shown in Fig. l, thus uniting the peripheries of the said anges, the one with the other, and greatlyincreasing their powers of resistance to strain.

What I claim as new, and desire to secure by Letters Patent, is-

The hub O, provided With angular corrugations f f, in combination with the' flanges d d,

having radial ribs lying directly opposite each other, and in line with the corrugations f and stay-rods j, substantially as described, and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence ot' two witnesses.

JOHN CLARK WANDS.
